Application filed 4Apii1 27, 1926. Serial No. 104,916.`

This invention relates to a hoisting appaf ratus which is more particularly intended vfor use Y in areaways, wells or elevator shafts which are arranged in the side walks between the building and theroadway or street adjacent thereto.

The'hoisting apparatuswhich has been in .use heretofore for elevating ash Abarrels and other materials from the basement of the building through the areaway and above the level of the side-walk has usually been provided with a verticailymovable mast section upon which a tackle oiawinchwas mounted,

whereby the operation vof lifting thebarrel vor other load was effected. Although such a device serves the purposeof elevating the load to a point above the side-Walk it was not wholly satisfactory because there still remained the burdensomeytask on the lpartof Vthe attendant to lift the ash barrel or other load from the side-Walkinto the top of the garbage wagon, ash wagon or other conveyance provided for that purpose@ lOrdinarily an areaway is notrsuliicientlydeep to permit of theemployment of a movable mast ysection as part of the elevating mechanism to secure 'a sufficient height of mast which will enable the load to'be lifted from the basement and deposited into the top of a wagon box.

The purpose of f the present y invention, therefore,is to provide means which in cooperation vy'ith the ,ordinary elevating and hoisting mechanism will permit of lifting the load suiiiciently high abovethe side-walk so that the same can be readily deposited into the top of the wagon box, which means kare capable of folding vertically so that the total height `of the same is considerably reduced Y an'dpermit of storing same Within an areaway `of normal height. In the accompanying drawings y y Figure 1 is a fragmentary vertical section Y of an areaway showing a hoisting mechanism mounted therein in its operative position and provided with my improvement wlierebyash barrels or the like may'beilifted through the areaway and above the side-walla suflicientdistanceso that the barrel may belifted a suiiicientheight-to discharge its .contents into lthe top of an ash: or garbage wagon.

, Similar charactersof reference indicate like parts inthe several views of the draw- The numeral 10 representsl an aieaway whichis arranged in the side-walk between ythe adjacent wall 11 of a buildingl and the pavement 12 on the roadway.` 1

Vithin this areaway and adjacent to one corner thereof is arranged a mast which forms kpart of the apparatus, which mast in its preferred construction comprises a lower fixed or stationary section 13 and an upper vertically movable section 14 which is guided on the lower mast section.,-Any approved means may be employed for raising, and low- .ering lthis movable mast` section with reference to the companion stationary section butV as thek same-forms no part of the present invention, an extended description of the same is not `deemed necessary.

On .the upper end of the upper mast section is pivotally mounted a horizontally swinging "ed on the armA 15 so as toturn about ahorizontal axis, a hoisting line 19 wound upon this drum and hook 8 or similaimeans arranged4 at the outer' end offthis hoisting line for attaching the latte'rto the barrelor other load which is to be lifted. This drum may be turned eitherforwardly or backwardly for an areaway with the coverremovedand the the purpose of Winding and unwinding the v hoistingpline bymeans of any suitable form of gearing, that shown in the drawings being of a well-,known type which is hand operated. i

As the line will hoist the-load only as far i load, such as as the drum o1 the winch the same ornnarily would rise only high enough to"` clear the top of the sidewalk and thus necessitate further manual labor n liftingegtheiloadpsuchi asy av can or barrelof ashes, from the side-Walk to the top of a Wagon box intended toA receive the same. p

Means are therefore provided whereby a an ash car 20, may be raised higher than would be possible by the mast `itself and thus permit of easily duin i'ng the contents thereof into the` box 21 o i an ash wagon arranged on the roadway immediately adj hoisting apparatus.'

Those additional* means or extension devices which give the hoisting apparatus the above mentioned added capacity', are constructed asfollowsn This extension consists gc'inerallyA of 'a boom: composed of a lower section which is capable oijfolding Yvertically with reference to the mast, and an upper section which is t'oldable with reference to the lower boom ""3 section and is adapted to carryl the hoisting line up tosuch a point thatthel'oad, such as an ash barrel, can be raised high enough `for dumping itsfcontents into the wagon box.

The lower boomsection inthe present case 'i :preferably ismade of elbow-shapeand consists of a lower normally horizontal arm 22 which is piuoted at its inner-endbymeans of `a'pin 23 to a base724- on'the upper side of `the mastlarm` 15, and. an upper normally `iiiirightV arm`25 projecting `upwardly from the outer `end of the'lower arm 22 and at an acute angle relatively1 thereto. The lower mast" section mayy be retained in this normal or operative position by afasteningdevice of' any suitable character but preferably by `means of a locking pin 26 passing through I corresponding openings 27 and 28 in parts "ofthe lowerai'm 22 vand the base 21.1-, as `shown in Figures l, 3 and 4i The upperseotion of the boom. comprises a -normally; upright arm. 29 which is pivoted atjits lower end by `means of a horizontal pin i3() to the upper end of the upper arm 25- of the lower boom section, and a normally horizontal arm 3l projecting forwardly from theupper end of. the upper arm section 29;

T'lie base 24,' the lower boomv section and the upperboom section are each preferably `made up of two members of angle iron arranged side by side andmade of the proper Violm. Each `of the boom sections has its angle Viron members connected Witheach 'other so" that in effect they produce an integral: structure, this `connection` being effected. `for example, by means of'cross rods ortie bolts as shown at32 with reference to the `lower boom sectionfin Figure l; y

' The uppei` boom section may be held in its normal operative position with reference "to theil'ower boom' section so asto f'orm an acent to the areaflway and the the two boom' upward' extensinn of theY litten or iis up-V 35 inthe lower and upper boom sectionsv when the boom is in its operative-position, as shownin` Figures l, 4V and 6, and? the same pin mayl also be engaged with correspondingf openings 34 and 36 in the lower" and u erV boom sections for the purpose of' holding sections in their foldedpesitions relatively to each other, as shown in p Figures 2 afnd.` i

0n the free or outerh end of the! arm of the upper boom section the same has pilvotally mounted thereon a guide pulley, or

sheave 3i? over whicl'rtl'ief` freel end- `of the hoistingline- 19 is adapted* to run so-that the' load which is attached to the hook 8 thereof may'behoisted anI added height equalj to the distance which the hoisting sllea'reV 357- is a'rranged above the hoisting drnmfi. i

Preparatory to beginning the operation of hoistingloads of material from the basement an dV through 'the areawayto" the wagen on the road-side, the upper mast' sectionlis raised to its highest position, the; lowerbooi'nv section' isstvimg from: its pendant position,`

shown, inFiguresZ and 5", into its upwardly projecting position, as shown` irr Fig-ure 4 and locked ther-eat by meansoi the-"pinA 36, and the. upper boom` section is swung" upwardly relatively lockingpin as shown in Figure 4. The boom as awhole rsnow'4 swung' inwardly so that the hoisting pulley 37 is over the areaway, as indicated inI Fig-ure 3; at W'Fii'cli'tirne the hoisting tackle may be o erst-ed for lifting the load,`.f=iu ch as a can o l" ashes, through the areaway and up to ai point immediately to the l'ower` boom section and locked in this position` by meansof the belowy the upper' hoisting pulley 3f?. After the load reaches this position the boom sections togetherwith the mast arm l-and the hoisting tackle may their be swung outwardflyuponA the pivot-16 asan` axisso as tocarry the ash can or other' loadI from a point over the areaway to a point:*adjacent` to the:

wagon box. Whiler in this position tfiecan suspended by the hoisting tiacklef may 4Be readily turnedby the'attendant into the position shown by dotted line in' Fi' re `1, whereb chargedi'nto the-open top of thefwagm box. 'Thereafterl the boom and associated parts `may beI again swung from al position in which it overshangs the pavement or curb, to

the contents ofthe ezrirrnay` e,l diga position 'n which same overslrangs theA areaway and the tackle may be' again 10M- ered for hoisting the next load. The boom therefore operates in the manner of a davit on ship board, whereby life-boats are first lifted' from the deck of a'ship and then swung laterally away from the ships side to permit of lowering the life-boat into the water.

After the hoisting a paratus has been thus employed the upper ld again folded relatively to the lower boom section and locked thereto, boom sections may be swung downwardly along side the upper position the boom sections are maintained by gravity, inasmuch as the reverse side of the arm 22 at this time rests onptop the base 24 and the elbow or angle of the lower boom section o'verhangs and clears the hoisting drum and associated parts. vWhile the boom is thus folded into its inoperative position, the upper mast section may be lowered and when the same is arranged in' its lowermost position the entire hoisting mechanism is below the top of the areaway so as to permit the door 9 to be closed. Y

By means of this boom extension on the ymast of the hoisting mechanism it is pos sible to hoist freight through the areaway easily and expeditiously and with a minin mum expenditure of manual labor, thereby materially reducing the cost of doing this work and also rendering the same more agreeable. Moreover the rapidity whereby ash cansand the like can be thus elevated and emptied into the ash wagon reduces the time in which such wagons are retained in the road-way and therefore avoids unneces-A sary'obstruction of the high-way. Furthermore, this apparatus is composed of com-l paratively few parts all of which' are strong and durable Vand not liable to get out 'of order and therefore reduces the cost of maintenance to a minimum.
